3 Claims.

This invention relates to robes,` or Warming bags, adapted to receive the lower portions of the bodies of wearers for `protection against cold.

' One object of my invention is to provide such a bag With an attached lap robe without having to dispense with an opening or placketdown the front of the bag. For convenience, such -an opening should extend up through the robe. The opening yin the bag proper may of course be closed with a Zipper or similar device. This being the case, Ia second object of my invention is to provide such a bag with a zipper or its equivalent that extends all the way up through the lap robe portion in order to prevent it from dividing into two portions that would fall off the wearers lap on either side. Another object of my invention is to include Ia cushion that will not depend upon the weight of the wearer to hold it in place, and that will, in fact, remain in place while the wearer is standing in spite of slight movements of the Wearers body. Another object is to make it possible for such a bag to be rolled into a compact bundle, and to provide means for holding or tying the bundle together. Still other objects willr appear as the specification proceeds.

In the drawing:

Fig. 1 is substantially a side perspective view with the fabric extended to show the construction more clearly.

Fig. 2 is a three-quarter front perspective view.

Fig. 3 illustrates the method lof using my invention.

Fig. 4 shows how the cushion remains in place on the seat or bench in spite of the downward pull of the Weight of the bag.

Fig. 5 pictures the entire combination rolled and tied in .a compact bundle. l

Figs. 6 and '7 show amodication of the cushion arrangement in which the under side of the cushion is Ecovered with fabric and the required frictional properties supplied by pieces of frictional material attached on the outside of the fabric, Fig. 6 being a fragmentary side View and Fig. rI a bottom view of the seat, showing the attached frictional material.

In the preferred form of my invention, the front and side portions, I and 2 respectively, extend upward above the top of the bag or sack proper to form a robe or apron 3 for the wearer, andthe back part of the bag is separated from the apron or robe to form a top surface covering 4 for the cushion 5 as well as a means 1 for connecting the cushion to the sack. A's the cushion is usually rounded at the back, as shown in Figs. 1 and 7, it is difficult to extend the top covering over the edges and to attach it smoothly to .the sides of the cushion. This difficulty may be vovercome, however, by slitting the material, or by cutting small portions of the fabric away so .that only narrow strips 6 of the material extend over-the- 5 edges. l y

As this warming bag rolls into a compact bundle, as shown in Fig. 5, it may easily be carried to foot-ball games and other outdoor eventsA that often taken place in chilly Weather.' After the 10 tying cord 8 has been released and the bagunrolled, it is immediately ready for use. The cushion 5 may then be placed on the seat 9, as shown in Figs. 3 and 4. In this preferred form, th-e cushion is formed of spongerubber, as indicated, an'd the bottom surf-ace of the rubber is left uncovered so that it will adhere to the bench or seat 9 upon which it is placed without being dislodged by the Weight of the bag. The portion 'l that connects the cushion to the bag has suflicient width be- 20 tween these members to -be used as a means of accommodatng the bag to benches and seats of different heights. Itis usually desirable to have the sides 2 of the bag come as close to the top of the seat as possible, and this condition can readily be 25 obtained by moving the cushion forward on high seats or backward on low seats.

If the wearer is using an overcoat, as is generally the case in weather that requires the use of a warming bag, the Zipper I0 may be opened, 30 permitting the user to have free access to the cushion without having to step into the bag or to draw the bag up around him. It is merely necessary for him to close the sides around his legs and pull up the Zipper. If the bag is being used without an overcoat, thereV is usually sufficient looseness to make it fairly easy to step into the bag Without undoing the Zipper, providing the apron partis folded down in front.

As the rubber cushion attached to my Warming bag produces considerable friction .between itself and the seat, the cushion will remain in plac-e in spite of slight bodily movements of the wearer, should he rise to his feet during the excitement of the sport that he is witnessing.

Frictional properties may be given to the under side of a cushion that is not made of rubber by attaching one or more pieces of rubber, leather or similar material to the under surface, as illustrated in Fig. '7. Fig. 6 shows a cushion that is 50 attached to the extension 4 of the material that forms the back of the bag; in fact, this material may form part of the cushion itself. In this modiiication, the frictional qualities required to make the cushion adhere to the seat may be supplied 55 Aso in the manner just described, and as illustrated in Fig. 7. The frictional properties of many materials adaptable to the ypurposes mentioned may be greatly increased by the use of a suitable dressing, many types of which are use'd to prevent belts from slipping in power transmission.

When the wearer has finished using the bag, the exi-ble cushion and apron may be folded inside of the bag proper and the entire combina,- tion rolled into a compact bundle, a-s shown in Fig. 5. This ligure also illustrates my preferred means for holding the bundle together, which consists of a cord and two special buttons that are a standard article of commerce and that have a peripheral groove adapted to grip the Vcord tightly where the cord is caused to cross itself within the groove. In Fig. 5cord 8 andv button II are lboth attached to the fabric at I4. Cord 8 then passes over the bundle, and into the groove of button I I, then longitudinally across the bundle and into thegroove ofV button I2, from the under side, and thence over and around the bundle and again into the groove of button I2, this time in a clockwise direction. The cord crosses` itself twice in the groove of button I2, causing it to be held rmly in place. The compact bundle thus formed may conveniently Ibe carried under .the

arm, or the portion of the cord that extends between the two buttons may be used as a handle.

`It will be evident that various modications may be made from the embodiments herein described without departing from the general spirit of my invention, and it is obviously possible to use many different designs, materials and constructions within the scope of the appended claims.

My claims are:

1. A combination comprising a flexible Lopentopped bag having a longitudinal opening; mean-s for closing said opening; a flexible cushion; and a section of flexible material interposed between and connected to said cushion and said bag; said cushion formed of resilient material that Will adhere to a substantially horizontal surface with suiiicient tenacity to over-come the weight of said bag; said `cushion and bag so constructed that the entire combination may be rolled into a compact bundle.

. 2. A robe comprising an open-topped bag having an opening therein extending from the top downwardly, and a cushion attached along its front edge to said bag `by means of a flexible strip, said strip being'secured to the bag vbelow the -top of the'bag, the undersurface of said cushion having high frictional properties.

3. A robe comprising an `open-topped'bag having a longitudinal opening therein and slits eX- tending downwardly from the top of said bag forming a flap, means for closing said opening, an'd a cushion attached to said flap, the under surface of said cushion having high frictional properties. 4 l
